Highest temperature in Chengdu on August 4?

Platform comparison

Market context

The event is the **highest daytime temperature** recorded at Chengdu Shuangliu International Airport on 4 August 2026, and the current 0% YES impression implies the crowd is treating this as effectively unpriced rather than impossible. For Chengdu in August, the baseline climatology is still hot and humid: long-run guides cluster around highs near 30–32°C, with some daily forecasts for 4 August sitting around 32–34°C and intermittent showers or cloud cover. That pattern matters because the market resolves on the single daily maximum, so even a brief afternoon spike can lift the outcome range despite rainfall elsewhere in the day.[2][5][6][11][14]

The historical framing points to a narrow band around the low-to-mid 30s Celsius, which is where comparable August forecasts and observed norms for Chengdu tend to converge. Recent market commentary also described trader focus around 34–35°C, with 36°C or higher appearing much less likely under humid, convection-prone conditions; that is consistent with August averages and with the idea that cloud breaks can cap extremes before the very highest bins are reached.[14][18][19] On the legal and access side, a Germany-facing trader would need to consider the GlüStV’s restrictive treatment of online gambling-style products, which can affect platform availability and account access, while US users should note that CFTC jurisdiction can reach event contracts depending on venue structure and location of use. A “no-KYC up to $1,500” setup means smaller participation can often happen with lighter identity checks, but once deposits, withdrawals, or cumulative activity pass the platform threshold, full verification may still be required, so accessibility is broad but not frictionless.[14]

For catalysts, the main watchpoints are the hourly temperature path, cloud cover, rainfall timing, and any late-day convective burst that could push the airport station’s daily maximum into a higher bracket. Traders should also pay attention to how the market’s source defines the settlement cut-off: it resolves to the highest temperature published for that station on Wunderground for the day, with revisions accepted only until the first datapoint for the following date is published, so late data updates can still matter. Because the settlement window ends at 12:00 UTC, the relevant live temperature peak in Chengdu’s afternoon and early evening local time is the key dependency, not overnight conditions.[14]
